The CLUSTER project develops criteria and recommendations for the definition of "CO2 stream concentrations" (cf. EU‐guideline 2009/31/EC), whereby CO2 from various sources is intended to be combined, integrated into a common transport pipeline and subsequently stored. A feasible solution is imperative as CO2 streams from different sources indubitably vary in many aspects, such as in their composition, variable mass flows, operation times and intensities. The effects of these temporal variations of mass flow and compositions in “Transport – Injection – Storage” sytem are the primary focus of the investigations in this project. The basis of these investigations is a model scenario of a regional cluster of CO2 sources, whose separate CO2 gas streams are combined, transported through a pipeline network and injected into a geological storage. In this case, the CO2 is stored in a fictitious offshore saline aquifer. Furthermore, as means of comparison with pipeline transport, transport of CO2 with ships to the offshore facility was also considered.
